Construction crews broke a water line servicing the Lexington Place subdivision near Mandeville Wednesday afternoon. Water service has been turned off to the area.

When service resumes, residents will be under a boil water advisory, St. Tammany Parish government said in a news release.

The line was broken around 2 p.m. It is not known when service will be restored, but the parish said it could take several hours.

The boil advisory "recommends that customers who wish to consume the water first boil it for at least one minute,'' the news release said.

Once samples show the water is safe to drink, Tammany Utilities will rescind the boil advisory, but that could take up to 48 hours, the parish said. Customers will be notified through signs in the neighborhood; an announcement will also be posted on www.stpgov.org.
